Be itknown that I, IVAN M. SCHNE'IBLE, a citizen of' the United States, residing at Greenwich, in the Vcounty of Washington' and State of NewYork, have invented cerv tain new and useful Improvements in Steri- A upon tofemployA hypodermic needles, haveex-v perienced considerable difficult in sterilizinginstruments ofthe kind al uded to, the

sterilization Vgenerally being effected ,at the bed-side of the patient, or under other co'nditionsv which render impractical, the use of. sterilizing devices of thesort fund'in lab oratories, physicians ofiices and elsewhere. The foregoing being understood, it may be stated` that it is the object of this inven-v tion tofpro-vide a simple means whereby hy.` podermicl needles may be sterilized, they device being soconstituted that, when the occasion forfitsuse has passed, it( maybe collapsed readily so as to occupybut little spacein the pocket or in the bag of a doctor or nurse.- f

The drawings show ymerely a typical embodiment of the invention, and it is to be understood: that, within the scope of what is claimed, changes lin proportions of parts, and other alterations which a mechanic might make, may be resorted to, without departing from the spirit of the invention.A

In the accompanying drawings Figure 1 is a side elevation disclosing a device constructed in accordance with the invention, the same being collapsed and in the position which it will assume when not in use;

Fig. 2 is a side elevation showing the structure as it willappear in use;

Fig. 3 is a transverse section, the parts being arranged as they will appear when the device is not in use;

Fig. 4L is a section taken approximately on the line 4-4 of Fig. 3.

In carrying out the invention, there is provided a fuel-holding base 1 which may be variously constructed. The base 1 preferably is a composite structure, embodying a block 2 of fabric, asbestos or other material which willnot conduct heat readily. A disk 3 is superposed on the block 2 and includes Specification of Letters Patent. Patented Sept. 20, '1921. Application med otob`er 29, 1915; serial No"3l 1,`1'2s. f

a depending' flange 4 engaging the periphery'of the with a depressionradapted to receive fuel of any kind. If desired," the fuel maybe in lock 2. vThe disk 3 is supplied the form of'a tablet' (not shown)` shaped to'k fit more' or I essfelo'sely in the depressions. 'V

The numeral v(Sfidenoftes a top vvwhich may` have acthickened rim 7, the ed 'e' ofthe rimV being threaded as denotedby t e numerals.'

The top 6is connected withthe base 1 in'any suitable way. IfVY desired, wpostsj 9 may, be employed to effect the' connection, the sts having reduced ends 10 passing throng the disk`3 and the block 2, andthroughfthe rim 7 of the top 6, the posts being butt-ended as atv11, to engage the rim 7 of the' top andthe block 2.' 'The particularv means specified for connectingthe vposts with theV other Vparts of the. structure is not insisted upon, but'the form shown will b e found toibe' useful. InT cidentally, it may be observedV that the lower ends of the osts 9 constitute' a'means for holding the base together. f Y

The invention comprises'an annular casing'12 threadedasshown atf14'fto cooperate with'the threads f8 ofthe rim 7 ofthe top' 6; At. its lower' end, thecasi'ng 12 may-be'sup; plied with a flange 16, to lthe upper surface of which a washer 17 is secured. Externally, the casing 12 is provided with ribs 15, to the end that the casing may be rotated readily.

When the device is not in use, the casing 12 is threaded downwardly on the rim 7 of the top 6 until theflange 16 abuts against the disk 3 of the base 1, the upper edge of the casing being substantially flush with the upper surface of the part 7 of the top 6. Obviously, the structure, when arranged as above described, is in compact condition, so that it can be carried in the pocket, in a compartment in a case, or elsewhere.

When the article is to be used, the casing 12 is rotated, and since the casing and the top 6 are threaded together as shown at 14-8, the casing will rise until it extends above the top 6, the top thenbecoming the base or bottom of a sterilizing receptacle, the side wall of which is formed by the casing. In the receptacle above defined, water or a sterilizing liquid of any kind may be placed, the needle being immersed in the contents of' the receptacle. The fuel lock'2 andthe disk 3' of the v in the-depression' is ilgnited, ang1 the lliquid eated su cient y toV in the receptacle is effect a sterilization. A

When the casing 12 Vis vele'vated'a's'above described, the flange 16 onv thefcasing resses the washer 17 against the under sur ace of, the rim 7 of the top 6, thus insuring a her.W metio joint between-.the casing 12 and the.v

the threads 14 and Bare formed with some care, the flange 16 and theV washer-17 may vnot be necessary, but, as acominercial propo- '.sition, it may vnot be expedient tol fash1on the threads with extreme care and exactness,

`1."A device of the class described com# prising an imperforate ydisk-like fuel-holding base; a top; means 'for connecting the base with the top, and a casing carried Yby the top and upstanding above the topf, to form a sterilizingreceptacle closed at its lower movableY e ectjja col- 2. A device of Vhe class described comprising a fuel-holding base; atop; means forconnecting the base with 'the top; and

a carried lby the top and upstanding above the top, to forma sterilizing receptacle closed at its lower end by the top, the

casing beingthreaded on thegperiphery of the top, whereby the casing may be moved toward the base to .efect a collapsing of the i device. v
